Abstract

Light emitting diodes have many positive features comparing with incandescent and fluorescent lamps like its small size; high luminous efficiency, long lifetime and reliability. That features increases the popularity of LEDs using in lighting. However there are many cheap, non-certified light emitting diodes bulbs in the market, where the parameters of the light emitting diodes bulbs are undeclared or declared incorrectly. The simple and low cost evaluation methods for evaluation of efficiency of light sources are presented in the paper.
